Macurco MRS-485 Modbus RS-485 Adapter

Conney #: 25321
MFR #: 70-2900-0012-1

The Macurco MRS-485 Adapter is an accessory used to convert the 4 to 20 mA analog signal from Macurco 6-Series type detectors to a digital signal for use with multipoint addressable systems. The Macurco MRS-485 simply plugs into the back of the detector and a single screw fastens it in place. The MRS-485 accepts the 4 to 20 mA output and is powered from the same connection as the detector. The MRS-485 has the ability to interface with building automation systems, control panels, or other control devices that accept Modbus communications.

Features include:

  • The Macurco MRS-485 interfaces the detector power and 4 to 20 mA output lines with a mounted connector
  • The MRS-485 monitors sensor type, gas level, and trouble status communications from any of the Macurco 6-Series detectors
  • Communication is on a Modbus serial line
  • Commercial type enclosure to protect and support the electronics
  • Tricolor LED indicates power, test, and communication status
